The description of the locations of jars is inaccurate if people use prebuilt hadoop package. In such cases, the jars should be under HADOOP_HOME and HADOOP_HOME/contrib/gridmix/.

A few new configuration parameters are added as part of MAPREDUCE-1936. Should we document those too? If you run Gridmix3 without any parameters, you would see these options. Alternatively, we can just say in the forrest documentation that information about additional configuration parameters are available through Gridmix command line help.

Hong, I agree that the documentation should reflect "as-packaged" paths rather than "in-source" paths, as the documentation
is for end-users of Hadoop, not Hadoop developers.
I favour explicitly describing the parameters from MAPREDUCE-1936 in the documentation. Do you want to update the patch?
